5. User Interface

M-9329 provides 2-wire digital UART port for communication of GPS position data

using NMEA protocol or MTK extension protocol. UART port is capable of 4800 to

115200 baud rate.

5.1 NMEA Protocol

M-9329 is default to support standard NMEA-0183 protocol. In addition, a series of

MTK extensions (PMTK messages) have been developed that can be used to provide

extended capabilities common to many applications.

5.2 NMEA Protocol format

M-9329 is capable of supporting following NMEA formats:

NMEA RECORD Description

GGA GPS fix data

GLL Geographic

GSA GNSS DOP and active satellite

GSV GNSS Satellites in view

RMC Recommended minimum specific GNSS data

VTG Course Over Ground and Ground Speed

ZDA Time & Data

6.3 Recommendation reflow profile

� We strongly recommend that this module should be designed to mount on top

side of motherboard with main chip together which process the final reflow.

� The maximum frequency of this module to pass reflow process should be no

more than twice, including repair operation, otherwise it may cause side effect to

the performance.

� Below is the recommend reflow profile referred to Main MTK chipSet.
